Said sides of seat I2, have notches at rear portions, saidnotches extending upward to approximately midway of the side face of theseat l2, as in Figure 4.

When the chair is in the open or extended position as in Figures 1 and2, the notches in the side faces of seat l2, fit over the latch bar [5,as shown in Figure 4, thereby locking the chair in position and furthersecured by the weight of the child and causing the back rest I! to slantto the rear, thus forming a comfortable position for the child. The trayIll is brought forward over the back rest H to rest upon the upper endsof the front legs 5 and side braces 8 and is then in the proper locationfor use.

When folding or collapsing the chair for storage or transportation, asshown in Figure 3, the tray I is swung over the back rest II, and thenthe rear portion of the seat 12, is pulled upward thereby releasing theseat [2 from the latch bar I in the back rest H, permitting the frontlegs 5, and rear legs 6, to be swung toward each other on the pivots andso collapsing the chair,

When the chair is being folded or collapsed, the novel arrangement ofthe sides of the seat 12, as in Figure 4, permit the seat 12 to slide tothe rear and over the latch bar [5, in the back rest I l,

, moving into a vertical position as in Figure 3,

thereby holding the front legs 5 tightly against the rear legs 6 and theback rest H, preventing the chair from being extended by any means otherthan further movement upward of the rear of the seat l2.

The safety strap I3 is. then connected to the tray as shown in Figure 3,positively locking the entire structure of the chair for transportation.

When the chair is extended to the open position a in Figures 1 and 2,the seat I2 is pulled forward until the notches in the sides of the seati 2 drop over the latch bar It in the back rest H, thereby securing theentire chair in the open position and ready for use. Movement of theseat l2 in this manner causes'the front legs 5, the rear legs 5 and theback rest H, to be ex tended to the proper positionfor use. The tray isis then brought forward over the back rest I! into position and securedby the safety strap :i3 fastened at its lower end to the front of theseat 12.

The legs 5 and 5 as shown in Figure 2, are so constructed or formed asto have their lower portion extended outward for a suitable distancethereby providing additional stability and sturdiness to the chair whilein use.

From the description of the invention herein described it will be seenthat provision has been 7 made for a collapsible or folding high chairwhich,

by means of a new and novel seat arrangement and other component partsof the chair, may be held in either an open or closed position withoutany other attached locking devices, levers or catches and using onlysaid seat and component parts of the structure to provide a moresatisfactory and easily operated high chair.

We realize that changes may be made and construction details variedwithout departing from the desires of the inventors or the range of theinvention herein described and we therefore present the following claimsas our invention.

We claim: 1. A folding chair comprising a pair of front legs, a pair ofrear legs pivotally connected at braces within the pivotal connectionsbeing in parallelogram relation, and a seat pivotally connected to thefront legs and supported by the back rest members.

2. A foldingchair comprising a pair of front legs, a pair of rear legspivotally connected at their upper ends to the front legs substantiallybelow the upper end of the front legs, a back rest having memberspivotally connected at their lower ends to the rear legs in the regionof the midportions of the rear legs, a pair of side braces pivotallyconnected to the upper ends of the front legs and extending downwardlyand rearwardly to pivotal connections with the back rest memberssubstantially above the lower ends of the back rest members, a seat,mean pivotally connecting the forward portion of the seat to the frontlegs and means attached to the back rest members for supporting therearward portion of the seat, the portions of the front legs, the rearlegs, the back rest members and the side braces within the pivotalconnections being in parallelogram relation, the seat having sideportions formed to provide clearance with the means for supporting therearward portion of the seat when the chair is in folded position withthe front legs and back rest members adjacent to each other and the seathanging vertically downwardly back of the means for supporting therearward portion of the seat, the seat hanging from the means pivotallyconnecting the forWa-r portion of the seat to the front legs.
